Reflectiv IR 80Xsolar window film

Heat rejection film from Reflectiv

An exterior ceramic film that rejects 71% of infrared and 66% of total solar energy while passing 72% of daylight. The right pick for double-glazed and Low-E units, which take film on the outside face to avoid thermal stress. The faint grey-blue cast all but disappears on the facade.

IR 80X takes the ceramic recipe outside: an external film in extra light grey blue that rejects 71% of infrared and 66% of total solar energy at a solar factor of 0.34, while passing 72% of visible light and blocking 99% of UV. Seen on the facade, the tint all but disappears.

External application is what makes it the safe route for sealed units: the sun's energy is stopped at the outer face before it can build up heat inside the cavity. Reflectiv's compatibility list says exactly that, simple glass from 4 to 10 mm, toughened glass and HR++ high-efficiency units, with plexiglass and polycarbonate possible after a compatibility test.

Durability is quoted at 10 years for vertical application in central Europe; exterior films age faster than interior ones because the weather works on them directly. Fire behaviour is Euroclass B-s1,d0, application needs 5°C or warmer, and rolls run 1.52 metres wide in 10 or 30 metre lengths.

Which glass it suits

IR 80X goes on the outside face and is the specified choice for double glazing and Low-E units, where an absorbing interior film would stress the sealed unit. The pane must be clean and grease-free, production batches should not be mixed across one elevation, and after thirty days it cleans like any glass, non-abrasive and ammonia-free.
